How old is your house, and do you still have any knob and tube wiring? Be aware that it is a fire hazard to have insulation touching knob and tube. We still had knob and tube up there, so that had to be replaced before we could have insulation blown in. It did make a noticeable difference in winter.

It was built between 1900 and 1920. There are some remnants of the old knob and tube but it’s not active. I plan on pulling it out while I’m up there
